The ASUS USB-N13 works as a great USB wireless adapter. It is hands down one of the fastest I have used. It also has some great range behind it.
However, as a wireless access point (under Windows 7) it leaves something to be desired. I am sure that ASUS will turn this around and fix it sooner or later, but for now I would not recommend its use with Windows 7.
Of course, for $24.99 at NewEgg.com, you are still getting a very fast Wireless Adapter; one that is actually smaller and lighter than the others I have here in the lab. It makes a great choice if you do not already have a wireless adapter in your laptop or PC.
